Solids.

3 Physical Properties of Lanthanides:
1. Silver-white metals that tarnish when exposed to air, forming their oxides.
2. They are small metal pieces that are soft.
3. Lanthanides are hard because of the atomic number.

3 Chemical Properties of Lanthanides:
1. Lanthanides react with water to liberate hydrogen (H2).
2. At elevated temperatures, lanthanides will burn.
3. Lanthanides react readily with most nonmetals and form binaries on heating with most nonmetals.

3 Interesting Facts on Lanthanides:
1. At one time, the lanthanides were called the rare earth elements.
2. They are a series of metallic elements.
3. The lanthanides are all similar in size.

2 Common Uses for Lanthanides:
These elements are commonly used in lasers and the making of sunglass lenses. Their compounds are used as catalysts in the production of petroleum and synthetic products.
